INIMICUS JAPONICnS (Cuvier and Valenciennes). 



Nanao, Misaki, and Tokyo markets. 



A series of specimens, mostly from the Tokyo market, ranging in 

 color from bright orange to deep reddish brown seems to indicate 

 that I. japonicus and /. aurantiacus are identical.

Otaru, Hakodate, and Tokyo markets. 



In an examination of a considerable number of specimens of tliis 

 species, certain variations in the arrangement of the lateral lines of 

 the breast and abdomen appear which serve to cast doubt on the 

 validity of //. ahuraco Jordan and Starks. The latter appears to have 

 been distinguished from H. otakii in not having the fifth lateral Unes 

 connected ^\•ith each other nor with the median line of the breast. 

 This character is not constant. In one example from Aikawa the 

 fifth line joins the median one posterior to the anal opening as usual, 

 and then sends a branch forward and outward. In another the fifth 

 Une ends near the anal opening while its fellow of the opposite side 

 joins the median line. A specimen from the Tokyo market has the 

 lines arranged as in otakii on one side and as in ahuraco on the other. 

 Lesser variations sometimes occur, the median line being more or less 

 irregular and broken, and the point of union between the median and 

 fifth lines being near the anal opening or far forward near the base of 

 ventrals. The color, fin rays, scales, etc., of a specimen from Hako- 

 date, having the lateral lines of H. ahuraco do not differ from those 

 of typical H. otakii. This particular individual has a large, black spot 

 on the posterior dorsal spines. 



HEXAGRAMMUS OCTOGRAMMUS (Pallas). 



Tide pools at Hakodate. 



HEXAGRAMMUS LAGOCEPHALUS (Pallas). 



One example from the market at Mororan. 

 Family COTTID.E. 



RIKUZENIUS PINETORUM Jordan and Starks. 



Thirty specimens were collected in the ]>ools at Hakodate. Tliey 

 resemble examples collected by the Bureau of Fisheries steamer 

 Albatross at moderate depths near shore in all particulars except 

 that they are darker in color. There are three ventral rays, large 

 orbital tentacles, and a pair of cirri near the edge of the maxillary.
